Airborne Lidar Data (2016 and 2021) Capturing Debris Flow Erosion and Deposition after the Grizzly Creek Fire in Glenwood Canyon, Colorado Airborne Lidar Data (2016 and 2021) Capturing Debris Flow Erosion and Deposition after the Grizzly Creek Fire in Glenwood Canyon, Colorado
This dataset contains lidar digital elevation models (DEMs). The lidar data were collected before (2016) and after (2021) the Grizzly Creek Fire, which occurred in 2020. The 2016 lidar was collected during a series of flights between 10 June and 7 October 2016. The 2021 lidar flight was conducted in full on 24 August 2021. The files are named with the following convention: Vendor_Year...

Select structure observations, model results, and model input parameters for debris-flow runout model simulations of the 9 January 2018 Montecito debris-flow runout event Select structure observations, model results, and model input parameters for debris-flow runout model simulations of the 9 January 2018 Montecito debris-flow runout event
This dataset contains three comma separated value files that represent a combination of previously published structure observations and select model results at the location of each structure centroid from a separate previously published simulation study. -"buildings.csv" represents the merging of structure damage observations published in Kean et al. (2019) and structure locations from...
Digital compilation of historical ice terminus positions of tidewater glaciers in Glacier Bay National Park and Preserve, Alaska Digital compilation of historical ice terminus positions of tidewater glaciers in Glacier Bay National Park and Preserve, Alaska
In coastal subarctic environments such as the fjords of Southeast Alaska, tidewater glaciers can control local hydrology, climatic patterns, ecology, and geologic hazards like landslides and consequent tsunami waves. Documenting and studying glacial retreat in fjords can help scientists understand the dynamic systems that are intrinsically tied to glacial ice processes and forecast...

Spectral reflectance data of rock and soil in southcentral Alaska Spectral reflectance data of rock and soil in southcentral Alaska
An ASD FieldSpec 4 Hi-Res NG Spectroradiometer was used to collect the reflectance properties of soil and rock in southcentral Alaska, USA (Figure 1) around the city of Anchorage (Figure 2) and the Prince William Sound (Figure 3). Reflectance is a property of the material being observed, being the ratio of the amount of light leaving a target to the amount of light striking the target...
Field-verified inventory of postfire hydrologic response for the 2020 CZU Lightning Complex, River, Camel, and Dolan Fires following a 26-29 January 2021 atmospheric river storm sequence Field-verified inventory of postfire hydrologic response for the 2020 CZU Lightning Complex, River, Camel, and Dolan Fires following a 26-29 January 2021 atmospheric river storm sequence
This data release is a field-verified inventory of postfire hydrologic response for the 2020 CZU (San Mateo–Santa Cruz Unit) Lightning Complex, River Fire, Camel Fire, and Dolan Fire following a 26-29 January 2021 atmospheric river storm sequence. Postfire hydrologic response types include a) no response, b) minor response, and c) major response. A “minor” response was deemed capable of...
Fault Rupture Mapping of the 6 February 2023 Kahramanmaraş, Türkiye, Earthquake Sequence from Satellite Data (ver. 1.1, February 2024) Fault Rupture Mapping of the 6 February 2023 Kahramanmaraş, Türkiye, Earthquake Sequence from Satellite Data (ver. 1.1, February 2024)
This data release contains two datasets that depict fault rupture on the East Anatolian and Çardak faults resulting from the Mw7.8 and Mw7.5 earthquakes in Turkey (Türkiye). It contains two additional datasets that describe satellite imagery coverage and observation gaps. The 6 February 2023 earthquake sequence caused >500 km of combined surface rupture on the primarily left-lateral...
Tadpole Fire Debris Flow and Wood Collector Measurements May 2021 Tadpole Fire Debris Flow and Wood Collector Measurements May 2021
This is a dataset of location and photo data for the debris flow deposits measured in the Tadpole Wildfire. The data were collected using the ArcGIS Collector application by multiple individuals. The original data are stored in a geodatabase here, and the geodatabase has the following fields: Latitude (decimal degrees), Longitude (decimal degrees), Elevation (meters), GlobalID (a unique...

St. Louis Geotechnical Database, v2003 St. Louis Geotechnical Database, v2003
The St. Louis area has experienced minor earthquake damage at least 12 times in the past 205 years. The St. Louis metropolitan area, with a population of about 2.8 million, faces earthquake hazard from large earthquakes in the New Madrid and Wabash Valley seismic zones, as well as a closer region of diffuse historical and prehistoric seismicity to its south and east. Also, low...
Data for Laboratory simulation of earthquake-induced damage in lava dome rocks Data for Laboratory simulation of earthquake-induced damage in lava dome rocks
We performed laboratory time-dependent creep and stress-oscillation earthquake simulations in uniaxial loading in compression and tension on four blocks of porphyritic dacite collected from pyroclastic deposits of Mt. Fugen, of the Unzen-dake volcanic complex in Japan (referred to as ‘Unzen volcano’). Experiments were carried out in the Experimental Volcanology and Geothermal Research...
